Various experimental models have been developed to test interventional neuroradiologic techniques. Most have been used to test various devices and embolic materials, and a small number of models have been designed for teaching or training purposes. Experimental models in endovascular techniques have seldom been used to stimulate disease processes in order to facilitate their understanding.

BACKGROUND Percutaneous transluminal angioplasty and stenting (endovascular treatment) can be used to treat carotid stenosis, but risks and benefits are uncertain. We therefore compared endovascular treatment with conventional carotid surgery. METHODS In a multicentre clinical trial, we randomly assigned 504 patients with carotid stenosis to endovascular treatment (n=251) or carotid endartere...

Background and Aim: Endovascular neurosurgery is widely accepted as a useful modality for the management of neurovascular disorders. This retrospective study aimed to evaluate the causes of diagnostic and therapeutic neuroendovascular procedures, as well as the prevalence, type, location and management of vascular pathologies observed in Firoozgar Hospital, Tehran City, Iran. Methods and Mater...

BACKGROUND Recent recommendations to screen for abdominal aortic aneurysm (AAA) in high-risk populations and the rapidly increasing use of endovascular repair have led to increased interest in evaluating the effectiveness of treatment options for patients with AAA. PURPOSE To compare the effectiveness of treatment options, including active surveillance, open repair, and endovascular repair, f...

OBJECTIVE To compare the costs and benefits of open versus endovascular repair of abdominal aortic aneurysm (AAA). METHODS A consecutive series of 29 elective patients (open treatment, N = 20 and endovascular treatment, N = 9) were compared retrospectively. RESULTS Operating time was significantly shorter for endovascular treatment (mean 90 vs. 125 min, p = 0.026). No endovascular procedure...

The treatment of acute ischemic stroke (AIS) in the setting of intracranial large artery occlusion (LAO) with intravenous tissue plasminogen activator (IV-tPA) is associated with low rates of recanalization and high rates of neurological morbidity and functional dependence. Endovascular intervention, particularly mechanical thrombectomy, is a promising therapeutic adjunct to IV-tPA for the trea...

OBJECTIVE To document mortality after endovascular repair of ruptured abdominal aortic aneurysms (RAAAs). DATA SOURCES MEDLINE and EMBASE databases. STUDY SELECTION Articles that reported data on mortality after endovascular repair of RAAAs were identified. Only patients with true ruptures were included. Additionally, information on mortality after concurrent open repair was sought. DATA ...

Mycotic aortic aneurysms account for 1-3% of all aortic aneurysms. The management of this disease is controversial. Since open surgical repair is associated with high morbidity and mortality rates, endovascular aneurysm repair is an alternative treatment method with promising early and midterm outcomes, although its long-term durability is unknown. Secondary aortoenteric fistulas may occur iatr...

BACKGROUND The impact of high-fidelity simulators as an adjunct for endovascular training of general surgery residents has not yet been defined. The purpose of this study was to evaluate general surgery resident perspectives on the value of a simulator-based endovascular training program by using various measurement tools. METHODS General surgery residents in postgraduate years 1 to 5 (n = 50...

BACKGROUND The management of hemorrhage shock requires support of central aortic pressure including perfusion to the brain and heart as well as measures to control bleeding. Emerging endovascular techniques including resuscitative endovascular balloon occlusion of the aorta serve as potential lifesaving adjuncts in this setting. The Endovascular Skills for Trauma and Resuscitative Surgery (ESTA...
